TEPC MEASUREMENTS AND MONTE CARLO CALCULATIONS FOR EVALUATING AMBIENT DOSE EQUIVALENT RESPONSE IN MIXED RADIATION FIELDS AROUND THE SHIELDED AREA OF A CARBON ION ACCELERATOR

摘要

The tissue equivalent proportional counter is a versatile instrument used to determine the absorbed dose and the quality of an unknown radiation field, but it does not directly measure the operational quantity ambient dose equivalent H~*(10). In this paper, simulated and measured values of H~*(10) are compared, and some corrections are applied in order to give a reliable estimate of H~*(10) in a complex radiation field generated by high-energy carbon ions.
